There's a parent pointer in css.cgroup, so you shouldn't need a
separate one here.

Most cgroup subsystems define this structure (and the below accessor
functions) in their .c file rather than exposing it to the world? Does
this subsystem particularly need it exposed?

kcg or just cg would be a better name?
